		<title>Introduction</title>
		<para>&okular; is a &kde; universal document viewer based on the code of the &kpdf; application.
			Although being based on &kpdf; code, &okular; has some unique features such as overview mode,
			improved presentation support and annotation support.
		</para>
<!--
		<para>
			The PDF format is widely used for publishing documents that are
			mostly not meant to be edited again. &okular; is only a viewer
			for these files and therefore it doesn't provide any functionality
			to edit or create PDF documents.

			<title>Opening Files</title>
			<para>
				To view any supported file in &okular;, select <menuchoice><guimenu>File</guimenu><guimenuitem>Open...</guimenuitem>
				</menuchoice>, choose a supported file in the dialogue and click <guibutton>Open</guibutton>.
				Your file should now be displayed in the main window.
			</para>
			<para>
				If you have already opened files in &okular; before, you can quickly access them by selecting them in
				the <menuchoice><guimenu>File</guimenu><guisubmenu>Open Recent</guisubmenu></menuchoice> menu.
			</para>
			<para>
				After having a file opened you probably want to read it and therefore navigate through it. Go to the
				<link linkend="navigating">next section</link> to learn more about this.
			</para>
		</sect1>
		<sect1 id="navigating">
			<title>Navigating</title>
			<para>This section describes how you can navigate through a document in &okular;.</para>
			<para>
				There are multiple ways of scrolling the viewing area. One is to use the 
				<keycap>Up Arrow</keycap> and <keycap>Down Arrow</keycap> keys. You may also use
				the scrollbar, your mousewheel or the <keycap>Page Up</keycap> and <keycap>Page Down</keycap>
				keys.
			</para>
			<para>
				Another way is to hold the &LMB; down at any place on the document while dragging the mouse in the
				opposite direction of where you want to move. This procedure only works if the Browse Tool is
				enabled, which you can select by choosing <menuchoice><guimenu>Tools</guimenu><guimenuitem>Browse Tool
				</guimenuitem></menuchoice>.
			</para>
			<para>
				The navigation panel on the left side of the screen enables two more ways of navigating
				through a document:
			</para>
			<itemizedlist>
				<listitem>
					<para>
						If you click on a page thumbnail the viewing area will be brought to
						that page.
					</para>
				</listitem>
				<listitem>
					<para>
						If the document has a table of contents, clicking on a table
						of contents item will bring the document to to the page linked to that
						item.
					</para>
				</listitem>
			</itemizedlist>
			<para>
				Some documents have links. In this case you can click on them and the view will
				change to the page it links to. If the link is to a web page or some
				other document the default &kde; handler for that format will be invoked.
				For example, clicking on a link pointing to <quote>http://www.kde.org</quote>
				will open the web page in the default &kde;'s web browser.
			</para>
			<para>
				Additionally, you may use the following functionality to quickly move to specific places
				in the document:
			</para>
			<itemizedlist>
				<listitem>
					<para>
						You can go to the first page of the document using 
						<keycombo action="simul">&Ctrl;<keycap>Home</keycap></keycombo> or
						using 
						<menuchoice>
							<guimenu>Go</guimenu>
							<guimenuitem>First Page</guimenuitem>
						</menuchoice>.
					</para>
				</listitem>
				<listitem>
					<para>
						You can go to the last page of the document using 
						<keycombo action="simul">&Ctrl;<keycap>End</keycap></keycombo> or
						using 
						<menuchoice>

							<guimenuitem>Last Page</guimenuitem>
						</menuchoice>.
					</para>
				</listitem>
				<listitem>
					<para>
						You can go forward in the document using <keycap>Space</keycap> or <keycap>Page Down</keycap>.
						To go to the next page of the document use the <guibutton>Next Page</guibutton> Toolbar
						button or 
						<menuchoice>
							<guimenu>Go</guimenu>
							<guimenuitem>Next Page</guimenuitem>
						</menuchoice> in the menubar.
					</para>
				</listitem>
				<listitem>
					<para>
						You can go back in the document using <keycap>Backspace</keycap> or <keycap>Page Up</keycap>.
						To go to the previous page of the document use <guibutton>Previous Page</guibutton> Toolbar
						button or 
						<menuchoice>
							<guimenu>Go</guimenu>
							<guimenuitem>Previous Page</guimenuitem>
						</menuchoice> in the menubar.
					</para>
				</listitem>
			</itemizedlist>
		</sect1>
		<sect1 id="presentationMode">
			<title>Presentation Mode</title>
			<para>
				The Presentation mode represents another way to view documents in &okular;. It can be
				enabled in
				<menuchoice><guimenu>View</guimenu><guimenuitem>Presentation</guimenuitem></menuchoice>.
				It shows the document on a page per page basis. The pages are shown with
				zoom to page, that means all the page is visible. 
			</para>
			<note>
				<para>
					&PDF; documents can even specify that they are always opened in presentation mode.
				</para>
			</note>
			<para>
				When in presentation mode, you have an helper bar located on the top of the screen. Just move
				the mouse cursor to the top of the screen to make it appear.
			</para>
			<para>
				To navigate between
				pages you may use the &LMB; (next page) and the &RMB; (previous page), the mouse
				wheel, the arrow icons or the line edit in the top bar,
				or the keys specified in the <link linkend="navigating">Navigating</link>
				section.
			</para>
			<para>
				You can exit presentation mode at any time by pressing the <keycap>ESC</keycap> key or clicking
				the <guiicon>Quit</guiicon> icon in the top bar.
			</para>
			<para>
				You can also draw on the current page with a pencil. Click on the
				<guilabel>Toggle Drawing Mode</guilabel> icon in the top bar to enable or disable the possibility
				of draw in the presentation mode. The drawings are cleared automatically when switching to
				another page, or manually selecting the <guilabel>Erase Drawings</guilabel> icon in the top bar.
			</para>
			<para>
				The presentation mode has support for more than one screen in a multi-monitor configuration. 
				With more than one screen a new button will appear in the top bar, with the icon of a screen: 
				this is a drop down box that allows you to move the presentation to any of the other available screens.
			</para>
			<para>
				Presentation mode has some configuration options, you can find their
				description in the chapter <link linkend="configpresentation">Configuring &okular;</link>.

		<sect1 id="embedded-files">
			<title>Embedded Files</title>
			<para>
				If the current document has some files embedded in it, when you open it a yellow bar
				will appear above the page view to notify you about the embedded files.  
			</para>
			<screenshot>
				<screeninfo>The embedded files bar</screeninfo>

			<para>
				In this case, you can either click on the link in the text of the bar or choose
				<menuchoice><guimenu>File</guimenu><guimenuitem>Embedded Files</guimenuitem></menuchoice>
				to open the embedded files dialog. The dialog allows you to view the embedded files and
				to extract them.
			</para>
		</sect1>
		<sect1 id="annotations">
			<title>Annotations</title>
			<para>
				&okular; allows you to review and annotate your documents.
				Annotations created in &okular; are automatically saved in the internal local data folder
				for each user.
				&okular; does not implicitly change any document it opens.
			</para>
			<para>
				Since &kde; 4.2, &okular; has the "document archiving" feature. This is an &okular;-specific format for carrying the document plus various metadata related to it (currently only annotations). You can save a "document archive" from the open document by choosing <menuchoice><guimenu>File</guimenu><guisubmenu>Export As</guisubmenu><guimenuitem>Document Archive</guimenuitem></menuchoice>. To open an &okular; document archive, just open it with &okular; as it would be &eg; a &PDF; document.
			</para>
				<note>
					<para>
						Due to DRM limitations (typically with &PDF; documents), adding, editing some properties
						or removing annotations could not be possible.
					</para>
				</note>
			<sect2 id="annotations-add">
				<title>Adding annotations</title>
				<para>
					To add some annotations to the document, you have to activate the annotating toolbar.
					This is done by either selecting
					<menuchoice><guimenu>Tools</guimenu><guimenuitem>Review</guimenuitem></menuchoice> or
					pressing <keycap>F6</keycap>. Once the annotating toolbar is shown, just press one of
					its buttons to start constructing that annotation.
				</para>
				<note>
					<para>
						The annotating toolbar can be docked in any side of the viewing area: just drag it to
						move it to another place.
					</para>
				</note>
				<note>
					<para>
						Activating the annotating toolbar will make you switch to the Normal Mode.
					</para>
				</note>
				<para>
					You can stop the construction any time by pressing again on the button of the
					annotation you are constructing, or by pressing the <keycap>ESC</keycap> key.
				</para>
				<para>
					The newly constructed annotation will have as author the author you set in the
					<guilabel>Identity</guilabel> page in &okular;s
					<link linkend="configure">configuration</link> dialog.
				</para>
			</sect2>
			<sect2 id="annotations-remove">
				<title>Removing annotations</title>
				<para>
					To remove an annotation, just click on it with the &RMB;, and select
					<guimenuitem>Delete</guimenuitem>.
				</para>
				<para>
					When removing the annotation, its window will be closed if open.
				</para>
				<note>
					<para>
						This option could not be enabled because the document does not allow removing
						annotations.
					</para>
				</note>
			</sect2>
			<sect2 id="annotations-edit">
				<title>Editing annotations</title>
				<para>
					To edit an annotation, click on it with the &RMB; and select
					<guimenuitem>Properties</guimenuitem>. A dialog will appear with the general
					annotation settings (like color and opacity, author, &etc;) and the settings specific
					to that annotation type.
				</para>
				<para>
					To move an annotation, hold down the &Ctrl; key, move the mouse pointer on it and 
					then start dragging with the &LMB;.
				</para>
				<note>
					<para>
						Depending on the document permissions (typically with &PDF; documents), some options
						can be disabled.
